Appficatioa filed February 28, 1916.

'1 0 all whom it may concern:

lie it; known that we, JOHN SELLERS BAN- lication mechanisms. The invention refers the line ustification more particularly to indicating mechanism, and has for its chief object to improve or simplify the construction of part of this mechanism.

The machine to which the invention is particularly applicable is that disclosed in Patent No. 944,405, Dec. 28, 1909, and the invention is an improvement on certain parts of the justification mechanism described in tlle above specification and shown in the drawings annexed thereto.

According to the machine described in the specification of said patent, the unit or set value of each character or space is recorded by a line measuring mechanism and as each justification space is registered or recorded there is operated a space counter which moves in relation toa justification indicator or chart so that the justification fraction necessary for the justification of the composed line may be readily ascertained by the operator. It is not deemed necessary to give a detailed description of the line indicating justification tmechanism set forth in the aforesaid patent as such mechanism is now in common use, and a detailed description thereof can also be obtained by reference to the patent. It is sufficient for the present purpose to state that the justification space counter comprises a longitudinally moving bar furnished with a pointer and a rack or teeth. One or'more liftin pawls which engage the teeth are contro led by a motor which is operated automatically to raise the Specification of Letters Patent.

in that it renders it a rela t and lengthy operation to re move the space counting bar or to disengage it from the 1 land controlled and automatic mechanisms when it is desired to remove the bar for cleaning, renewal, or other purposes.

It is the chief object of the present invention to so construct the parts cooperating with, acting upon,

count ing bar,

readily and easily when the necessity and operated by the space that the latter can be removed required, Without of removing or interfering with adjacent parts.

he autom anism as her atic shift and throw-out mechetofore employed, comprises a shift valve controlling the punch actuating motors and the space-counting bar motor, which valve is acted upon by a lever adapted to be operated by the space-counting bar and also arranged to be operated by a longitudinally movable bar controlled by a hand actuated rod or device.

According to the present invention there is interposed between the shift-valve controlling lever and the space bar a connector member which in its normal position is act c-d upon by the space bar and the hand oper ated bar to operate the lever. and so contrivcd that it can be moved relatively to the controlling lever to be disengaged from and release the space-counting bar to allow the latter to be removed from the machine but when released it will automatically take up its normal position again.

Referring to the accompanying drawings:

Figure l is a perspective elevation of the space counting bar and the parts connected with it, and, apart from the hand controlled device bove referred to, the mechanism agrees pr-.:ctically with that described and illustrated in the aforesaid patent.

Fig. 2 is a detailed. view of part of the mechanism shown in Fig. 1.

Fig. 3 is a view similar to Fig. 1 showing the improved connection intermediate the valve operating lever and space-counting bar.

Like characters of reference throughout the several figures indicate the same parts.

The parts thus far described and the reference numbers indicating such parts correspond to the parts, and indicating numbers in the aforesaid patcut to which reference may be had for a description and illustration of cooperating parts of the machine.

it) is a. vertically movable bar adapted when elevated to engage the hook 200 and through it to move the lever 201 and valve 198. This bar 10 is manually controlled through the medium of a knob or finger piece or rod 11 mounted to slide in bearings in the frame and provided with a cam or inclined face 12 for cooperation with the lower end of the bar 10.

Referring now to Figs. 3 and 4 it will be 081} that a lever 201 is substituted for the lever 201 of the prior arrangement shown in Fig. l and upon the inner end of this lever there is pivoted at 14 a three arm lever, one arm 13 of which forms a finger piece while the arm 15 is adapted to rest on the lever 201 and the arm 16 projects into position to coiipcratc with the shoulder IT on the space bar 85 and to be cted on by the upper end of the manually controlled bar 10. The three armed lever forms a releasable extension of the lever 201 and may be tripped to move the arm. 16 out of the path of the shoulder 17 on the space bar by moving the arm l3 upwardly. Such movement causes the lever 201 to tilt on its pivot slightly and the rod 10 to move laterally at its upper end, the rod being loosely mounted in its guide frame to permit of such lateral movement.

In the mechanism, as shown in Fig. l, each time a justification space key is actuated by the operator, air passes to the motors of the justification space-punches and also to the motor acting on the arm i l aises the lifting pawl so. which, engaging the teeth of the justification space counting bar 85, raises the latter through one division. Should the operator, after the predetermined number of justification spaces that are to be placed in a line is reached, again touch. the justification space key, the bar 85 in rising will lift the hook 200 through the engagement of shoulder 17 on the bar with the nose of, the hook. and the hook will cause the lever 301 to be turned on its fulcrum (l and. operate the valve 198. The valve 1%, when so operated allows air to pass to shift the valve 20 so as to close the communication of the space signal keys with the space signal punch motors, and transfer the communication to the punches of an ordinary space. The motor 90 receives its motive fluid through one of the justification punch Inotors, so that when the power is shut oli from this motor by the operation of valve Lll, no further movement of the bar 55 can take place.

Should the operator, before the prede termined number of justitication spaces has been reached, desire to prevent further justification spaces from being recorded in the line, he moves the rod 11 in the direction of the arrow in Fig. 1, so that the cam or inclined surface 12 on this rod engages the end of the rod or bar 10 and raises it. The raising of the bar 10 brings it upper end into engagement with the hook 200 and elevates it, thereby operating the lever 201 and the valve 198 in. the same manner as if the hook had been elevated by the bar The connection of the bar 10 with the hook 200 is shown clearly in Fig. 2. As the nose of the hook is in the path of the shoulder 17 on the bar 85, the bar cannot be removed without the hook being first removed. The hook cannot be removed until the bar 10 has been removed, so that if it is desired to remove the space counting bar,

several parts of the machine have to be first removed.

With the l'llBUl'lilHiSlll of the present invention as shown in Figs. 3 and 4. the hook is dispensed with, and the releasable extension is mounted on the lever 201. \Vith this arrangement when the predetermined number of justifying spaces have been inserted in the line the shoulder on the bar 85 engages the nose of the arm 16, and the continued upward movement of the bar earrics the lever 201 with it to operate valve 198, since the arm 15 resting on the lever 201" prevents the three armed lever from turning on its pivot.

Similarly, should the operator move the rod 11 the bar 10 is lifted, and in rising engages the lever arm 16 to raise it and turn the lever 201 upon its pivot.

\Vhen it is desired to remove the bar 85 it only necessary to turn the three armed lever on its t'ulcrmn by pressing the third arm 13 upwardly. Such pressure on the arm 13 will cause the lever Z01 to tilt and will move the rod it) laterally slightly and the arm ll) will be turned clear of the bar 85, thereby permitting the bar 85 to be re moved quickly and easily and without disturbing or removing or disassembling any other parts of the machine. Moreover, the connector lever, when released, as after the bar has been withdrawn, automatically takes up a position ready to slip over the shoulder 17 without manipulation on the part of the operator when the bar 85 is returned to its holder.
